as you can see i have two oval holes in the plywood, the plywood was later covered with brown matching rexine, and two speakers were fitted with speaker grilles on top to give them a sleek look,. and this piece of plywood was also re-inforced with two elongated metal square pipes (1/2 of inch) this was to prevent sagging. , i will see if i have any pictures,, and if i have, they will be uploaded.
